While the Highland work was still going on, in 1888
Peach and Horne resumed their work on the Southern Uplands. In 1878
and subsequent years, Lapworth had shown that the original survey
of the Ordovician and Silurian was unsatisfatory. Peach and Horne
began their revision with the Moffat sheet (16) and the Loch Doon sheet (8), which had been surveyed but not published.

These sheets were then issued in 1889 and 1893. Thereafter, at odd
times during the autumn and spring seasons, when work was impossible
on their Highland ground, they gradually extended their search and
made exhaustive examination of most of the important field exposures,
adding notes and lines to the original six-inch maps. Peach made
himself an authority on the palaeontology, in particular the graptolites
and identified them with precision and accuracy. He also drew up
the cross-sections with which the great Memoir of 1899 is illustrated.
Horne, meanwhile, wrote the text and the work on the petrology of
the igneous rocks was done by Teall. Though produced under less than
ideal conditions the Memoir stood for fifty years before any of its
ideas were challenged: surely a great tribute to the men who produced
it.
